LAMP-SHADE, GLOBEAND GUARD HOLDER FOR COIl'DUIT-OUTL'ET BOXES.

Application filed March 19,1928. Serial No. 262,774.

This invention relates to a combined lamp shade holder, globe and guard for electric lamps and fixtures and has for its object a particularly simple and eflicient construction by which the lamp shade holder, globe and the guard are interchangeably mountable on the fixture, the globe interchangeably mountable on the lamp shade holder and the guard, and the guard interchangeably mountable on the lamp shade holder and fixture.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is ha d to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary side elevation,

partly in section, illustrating a lamp shade holder, guard and globe applied to a fixture or base as a conduit outlet box.

Figure 2 is a View similar to Figure 1 showing a lamp shade holder and globe applied to the base or fixture, the guard being omitted.

Figure 3 is a view similar to Figure 1 showing the guard and globe applied to the fixture or base, the lamp shade holder being omitted.

Figure l is a view similar to Figure 1 showing the globe applied directly to the base or fixture with the lamp shade holder and guard being omitted.

Figure 5 is an elevation of parts seen in Figure 3, the fixture or base being omitted.

Figure 6 is an end view looking upwardly of the guard shown in Figure 5.

1 designates a base as a conduit outlet box having an opening at one side which is surrounded by a cylindrical flange 2.

3 is a lamp shade holder having a ring 4 for interfitting with the cylindrical flange 2 and also having a cylindrical flange 5 of an internal diameter the same as the flange 2.

6 is a lamp guard having a ring 7 fitting the cylindrical flange 5 of the lamp shade holder and hence, also capable of interfitting with the flange 2 of the outlet box interchangeable with the ring 4 of the lamp shade holder, the guard also having a cylindrical flange 8 of the same internal diameter as the flanges 2 and 5 of the outlet box and the lamp shade holder.

9 is a globe having a ring or collar 10 interfitting and interlocking with the cylindrical flange 8 of the guard and hence, interchangeably interfitting and interlocking with the flange 5 of thelam p shade holder, or interfitting and interlocking with the flange 2 of the outlet box intercl'iangeably with the rings 4- and 7 of the lamp shade holder and the guard.

11 is a lamp socket mounted in the conduit outlet box within the flange 2, the socket being held in position by a plate 12 which overlies an internal seat 13 at the base of the flange 2 and which may be held in position by any one of the rings 41, 7 and 10 whichare interlocked with the flange 2. The flanges and rings are usually threaded with coarse holder and the guard being omitted.

The guard may be of any suitable form, size and construction, it being in the form of a cage depending from the flange 8 and as having a lower end section 14 detachable for permitting access to the globe to remove it and replace it.

The section 14. is held in position by screws 15 extending through slots formed in lugs 16, in one of the transverse members 17 of the 'age, these slots having enlarged portions 18 to permit the section l l to be detached upon partial loosening of the screws and then turning the removable section 14 until the large portions 18 of the slots are in line with the screw heads.

Owing to the fact that the rings 4, 7 and 10 of the lamp shade holder, guard and globe are all the same size and capable of fitting the flange 2 of the outlet box, any of these parts can be used to the exclusion of the others and owing to the fact that the flanges 5 and 8 are of the same size as the flange 2 of the outlet box, any combination of the lamp shade holder and/or guard and/or globe can be used with the outlet box 1.

What I claim is:

1. The combination of a base having a cylindrical flange, a lamp socket mounted on the base within said flange, a lamp shade hold or having a ring for interlocking in the flange,

the lamp shade holder also having a cylindrical flange with an internal surface of the same diameter as the cylindrical flange of the base, a guard having a ring for fitting and interlocking with the flange of the lamp shade holder or the cylindrical flange of the base, the guard also having a cylindrical flange formed with an internal surface of the same diameter as the cylindrical flange of the base and a globe having a ring interfitting with the flange of the guard, all whereby the globe, guard and lamp shade holder are applicable interchangeably to the cylindrical flange of the base, and the globe is interchangeably mountable in the flanges of the lamp shade holder and the guard, and the guard is interchangeable mountable in the flanges of the base an'd the lamp shade holder.

2.' The'combination of a base having a cylindrical flange, a lamp socket mounted in the base within the flange, a lamp shade holder, a guard and alglobe, each having a ring interchangeably mountable in the cylindrical flange and the lamp shade holder and the guard having cylindrical flanges having internal diameters the same as the cylindrical flange of the base, whereby the rings of the globe and of the guard are interchangeably mountable in the flange of the lamp shade holder.

3. The combination of a base havin a cylindrical flange, a-lamp socket mounted in the base within the flange, a lamp shade holder, a guard and a globe, each having a ring interchangeably mountable in the cylindrical flange and the lam) shade holder and the guard having cylin rical flanges havin r internal diameters the same as the cylin rical flange of the base, whereby the rings of the globe and of the guard are interchangeably mountable in the flange of the lamp shade holder, the cylindrical flanges being internally threaded and the rings externally threaded.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, this 8th day of March, 1928.
